New Zealand's Olympic Games taekwondo campaign is over after Vaughn Scott lost his repechage fight in the men's 80kg class in London this morning.

The 22-year-old Aucklander got a chance to fight again because his first round conqueror Argentina's Sebastian Crismanich qualified for the final.

But Scott lost 11-6 to Afghanisatan's Nesar Ahmad Bahawi, scoring two points from offensive kicks and another from a defensive punch and three from penalties awarded against his opponent.

Scott was the only of the three New Zealand fighter to get a second bout in London. Logan Campbell (men's 68kg) and Robin Cheong (women's 57kg) were eliminated in the first round earlier in the tournament.

Crismanich, the Pan American Games champion, beat Scott 9-5 last night, dominating the first two rounds after a bright start by the Cape Town-born Kiwi.

The Argentine beat Bahawi 9-1 in the quarterfinals and Armenia's Arman Yeremyan in the semifinals and will fight Spain's Nicolas Hemme Garcia, the 2009 world championship runner-up, for the gold medal later this morning.
